Im thinking a samurai with dancer subjob might make a good combination.
Subjobs don't level at all. You can use any job as a subjob, but you need to level those jobs as a main job first. If you don't plan on going all the way with a job, leveling it to 49 will suffice since main/sub levels are capped at 99/49.
DNC as a subjob is mainly used for solo play, in particular in dynamis.

Also consider leveling RDM to 49, but don't bother leveling it further. It's the ideal subjob for mages and some cases melee, but noone wants it for high end since it lacks anything that isn't done better by other melee and mages. Oh, and the devs are adding two more jobs with RDM-like qualities in the next expansion.
RDMs have a lot of staying power, but unfortunately that goes both ways... the enemy isn't dying anytime soon either.
